Amberfish is general purpose text retrieval software, developed at Etymon
|
|
by Nassib Nassar and distributed as open source software under the terms
|
|
of version 2 of the GNU General Public License (GPL). Its distinguishing
|
|
features are indexing/search of semi-structured text (i.e. both free tex
|
|
and multiply nested fields), built-in support for XML documents using the
|
|
Xerces library, structured queries allowing generalized field/tag paths,
|
|
hierarchical result sets (XML only), automatic searching across multiple
|
|
databases (allowing modular indexing), TREC format results, efficient
|
|
indexing, and relatively low memory requirements during indexing (and the
|
|
ability to index documents larger than available memory). Z39.50 support
|
|
is available. Other features include Boolean queries, right truncation,
|
|
phrase searching, relevance ranking, support for multiple documents per
|
|
file, incremental indexing, and easy integration with other UNIX tools,
|
|
The architecture is also designed to permit proximity queries; however,
|
|
they are not fully implemented at present.
|
|
|
|
This port also includes the Porter stemming algorithm for suffix
|
|
stripping, available at:
